5 8 4 4 1 I O S L E N COTTON PICKING MACHINE Filed March 15, i950 may Patented Feb. 9, 1932 DAN NELSON, OF NORMAN, OKLAHOMA COTTON PICKING MACHINE Application filed March 15, 1930. Serial No. 436,176.

This invention relates to cotton pickers, and its object is to provide a light, easily operated, simple and efiicient cotton picker. Referring to the accompanying drawings,

which are made a part hereof and on which similar reference characters indicate similar parts,

Figure 1 is a view in elevation of the machine, Figure 2, a plan View of the same,

Figure 8, a vertical section through the fan, and Figure 4, a modified form of fan. In the drawings numeral 10 indicates a base which may be mounted upon wheels 11 and may be pulled by a tongue 12, the front end of which, if desired, may be bifurcated to fit around the body of an operator and be secured to the waist of the operator as by means of a belt 18. An engine 14 is securely mounted upon the base 10. The engine may be and preferably is a small internal combustion engine. A centrifugal fan 15 is mounted upon the base 10 and is driven by means of a belt 16 from a pulley 17 on the shaft of the engine 14. A hose or other con duit 18 is connected to the intake of the fan 15 and a sack 19 or other receptacle is connected to the discharge outlet 20 of the fan. As shown the sack 19 may be allowed to drag along the ground or, if found desirable, a trailer may be attached to the rear of the truck for supporting the sack with the cotton deposited in it. The hose or conduit 18 is preferably separated at its forward end into two flexible conduits 21 and 22 through whichthe cotton is drawn by suction into the fan and deposited into the receiving sack 19.

Instead of having the'fan 15 driven from the engine by means of the belt 16, under certain circumstances I may find it preferableto drive the fan directly from the shaft of the engine. WVhen so driven of course the speed of the fan will be the same as the speed of the engine. By the use of an intermediate driving belt 16, as shown, I am able to have the fan driven at any desired speed either greater than or less than the speed of the engine by varying relative size of the pulleys on the engine shaft and on the fan shaft.

In Figure 4 is shown a modified form of centrifugal fan in which the blades 21 are curved in the direction of rotation of the fan, the curved blades acting as a scoop to assist in moving the bolls of cotton toward the fan outlet.

It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit of the invention and therefore I do not limit myself to What is shown in the drawings and described in the specification but only as indicated in the appended claim.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

A cotton picker comprising a base mounted upon wheels to be easily manually conveyed, an engine mounted upon said base, a centrifugal fan mounted upon said base and driven by said engine, a large conduit connected to the intake of said fan said conduit parting at its forward end into two flexible cotton receiving conduits, a cotton receptacle detachably secured to the exhaust from said fan, and a tongue adapted to-bepositioned about the body of the operator for pulling said apparatus along as the cotton is picked, substantially as set forth.

In witness whereof, I have hereunto set my hand at Norman, Oklahoma, this tenth day of March, A. D. nineteen hundred and thirty.
